Description Jeremy Katz 2008-07-07 13:48:15 UTC
When getting to the office and plugging my laptop into the external display, I
do something along the lines of
  xrandr --output VGA --mode 1680x1050 --output LVDS --off
(either via command line or the gnome tool).  Recently, this started crashing
the X server.  Looking in the X.log shows a nice segfault backtrace

Only "odd" thing in my xorg.conf is a Virtual of 2048x2048 and wacom setup

Jeremy, is this still an issue? Looks like it was fixed with the patch below.

    modes: check the crtc is valid before using its desired modes.
    this fixes a crash I was getting on radeon rotate when gnome is running.
    I'm sure g-s-d was doing something bad, but really not crashing ftw.

Looks okay now, yeah
